Synopsis

Documentation

The class of a register. Used in the register allocator. We treat all registers in a class as being interchangeable.

Outputable RegClass Source #	This instance is just used for the graph colouring register allocator. Prefer using either `pprRegClass` or `pprRegClass`, which is more informative.

The register architecture of a given machine.

Constructors

Unified	Floating-point and vector registers are unified (e.g. X86, AArch64).
Separate	Floating-point and vector registers are separate (e.g. RISC-V).
NoVectors	No vector registers.
